The issue is pretty obvious: The function was introduced 2013 in Matlab
and nobody implemented it for Octave so far.  You can take a look at
Octave existing triangulation functions [1].

   tri = delaunay (P);
   triplot (tri, P(:,1), P(:,2));
   xlim ([0 9])
   ylim ([4 9])

Otherwise you should provide an example what you like to do and maybe
you can solve this issue with Octave's functions too.
